Abstract As the second functionary layer in forest hydrologic process,the litter plays an important role on water cycling in the forestland.In this paper,the hydrological characteristics of forest litter,including study content,research method and hydrological characteristics simulation during the hydrological process was summarized.The singleness of study content and laggard method were the main problems in inland;It was indicated that the field settled experiment would be the keystone to study the hydrological characteristics of forest litter;During the course of rainfall simulation for the hydrological characteristics of litter,the rainfall intensity should be changed;The water dynamics of litter was resulted by multi-hydrological processes and influencing multi-factors.The establishment of physics model and the determination of its parameters are important to understand the water dynamics of litter layer and forest management.
